Research on Ultrasonic Guided Wave Damage Detection in Internally Corroded Pipes with Curved Random Surfaces

open access: yesApplied Sciences
To accurately simulate the progression of pipeline corrosion, this paper proposes a three-dimensional corrosion modeling method for curved random surfaces based on spatial frequency composition.

Comparison of the collapse frequency and failure probability of buildings

open access: yesActa Polytechnica CTU Proceedings, 2022
In a previous study, the collapse frequencies and associated mortalities of buildings were compiled based on various publications. The investigation showed a considerable scattering of collapse frequencies depending on the countries.

Mechanisms and critical criteria of coverd karst collapses under extreme rainfall conditions

open access: yesCarsologica Sinica
In recent years, the increasing occurrence of covered karst collapses triggered by rainfall conditions has posed a threat to human life and property safety. According to field investigations and statistical data, the triggering factors of karst collapses

Corrosion-provoked collapse of the inclined belt conveyor bridge [PDF]

open access: yesFME Transactions
This paper presents the results of the holistic failure-based root cause analysis of a sudden collapse of the inclined belt conveyor bridge (IBCB), which is a vital subsystem of a steel mill raw material handling system.

Magnetized Dusty Black Holes and Wormholes

open access: yesUniverse, 2021
We consider the generalized Tolman solution of general relativity, describing the evolution of a spherical dust cloud in the presence of an external electric or magnetic field. The solution contains three arbitrary functions f(R), F(R) and τ0(R), where R

Reciprocal control of viral infection and phosphoinositide dynamics

open access: yesFEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

Does gravity induce wavefunction collapse? An examination of Penrose's conjecture [PDF]

open access: yes, 2013
According to Penrose, the fundamental conflict between the superposition principle of quantum mechanics and the principle of general covariance of general relativity entails the existence of wavefunction collapse, e.g.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

open access: yesFEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

Physics of Collapse and Terminating Events [PDF]

open access: yes, 1997
Various catastrophic phenomena, including the sawtooth, ELMs, High-beta collapse, etc., have been known in plasmas. The large scale deformation and transition take place abruptly, characterizing the spatio-temporal evolution of the plasma structure.
